MULTIPLE GRAMoPnoNE.

To all whom it may concern:

Be it known that I, ALEXANDER THoMAs MOORE, a citizen of the United States of America, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful lmprovements in Multiple Gramophones, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a multiple gramophone and particularly to a structure employing a plurality of sound boxes in connection with a single reproducing disk.

' The invention has for an object to provide means` In the drawing Figure 1 is a.side elevation of the invention, and Fig. 2 a top plan thereof.

Like numerals of reference indicate like .parts in -th several figures of the drawing.

.The numeral 1 designates a casing or box provided with a driving shaft 2 carrying a disk 3 upon which the record 4 is placed. This casing is also provided with a bracket arm 15 having a suitable bearing for a conducting tube 1 3 which is connected at its end next the disk with a collecting chamber 12. The outer end of the tube 13 is formed with a vertical extension having a bearing portion 14 at its lower end, while at its upper end a horn 16 maybe applied as shown in Fig. 2. u Projecting laterally from the chamber 12 vis a series of tubes 9 each provided with a face plate 8 conforming to the outline of a sound box 5 with which it contacts whenthe latter is lowered to bring the needle 6 carried thereby into cntapt with the record 4 upon the disk. These tubes 9 also carry astoppin 1,0 to limit the backward travel of the plates 7 carrying the boxes 5 when the lat'- 1 ter are moved out of operative position. The plate 7 is i tube 9 is also formed with an apertured nipple 11 to which a horn similar` to that shown at 16 may be applied if desired.

Specicat'ion of Letters Patent.

Application filed September 11, 1903. Serial No. 172,811.

Patented Sept. 3, 1907.

It will be observed from the foregoing that a series -of needles and their sounding boxes may be employed for engagement with a, single record for the purpose of causing the simultaneous reproduction of the various parts of the music thus securing a clearer, more accurate and efficient reproduction ofthe recorded sounds than can be secured by a single sound box. The construction also permits the conduction of the sounds from the separate boxes through the chamber into a single horn. l

It will be obvious that changes may be made in the details of construction and configuration without departing from 4.the spirit of the invention as defined by the appended claims.

The sound boxes are adapted to engage independent grooves of the'rccord tablet at differentvv distances from the center thereof and do .not `follow each other in the same groove. This adapts the device for use in connection with a tablet having a series ofcircumferentially disposed records 'thereon which may be thus simultaneously reproduced.

What I claim is:- 1. A device of the class ydescribed comprising a disk record tablet provided with independent record grooves thereon, a plurality 'of sound conveying tubes mounted upon a single pivot, and sound boxes carried by said tubes at dif- -ferent distances radially to the axial center of the tablet to engage independent record grooves on said tablet.

2. A device of the class described comprising a disk rec- Iord tablet, a. plurality of parallel sound conveying tubes mounted upon a single pivot, and sound boxes carried by said tubes at different distances radially to the axial center of the tablet to engage independent record grooves on said tablet and be thereby simultaneously fed across the tablet.

3. A device of the class described comprising a disk record tablet, a plurality of sound conveying tubes of equal 6. In a device 'of the class described, a plurality of tubes, a sound box mounted opposite an aperture i'n each tube, a chamber connecting said tubes at one end,`a casing and driving disk, abracket from said casing, a horn supported by said bracket, and a'connecting tube from the horn to said chamber.,

7. In a device of the class described, a casing, a 4bracket secured thereto, a pivoted tube mounted upon said bracket, a chamber secured 5o the end of said tube, parallel couducting tubes projecting from said chamber, plates pivoted to said conducting tubes, a sounding box carried by each plate, aV stop upon each conducting tube to limit the travel of said plate in one direction, and means to support a record adjacent to said box. p

8. The combination with a sound record disk provided with independent duplicate records disposed concentric and relative to each oth'er, of means mounted upon a single pivo`t and pijovided with a plurality of sound boxes disposed at diiterent distances from the center of the disk' to 10 independently engage said records und be simultaneously a l E fed thereby across said tablet.

In testimony whereof I aix my signature in presence ot two witnesses.
